Reset Button

• Reset. Press and hold the reset button for 5 seconds until the LED

indicator flashes Red 3 times quikly to clear the Wi-Fi information

(energy data will not be cleared). After that, the LED indicator will blink

Green and wait for pairing.

Note: If you want to clear the energy data, please delete the device and

wipe data on the app then add it again.

LED indicator

The LED status gives the following information of the power clamp:

3Installaion

Impoant safety information!

• The power clamp must be installed and seiced only by a qualied

electrical personnel.

• Do not touch the terminals of the device during testing.

• Turn o all the power supply for this equipment before installing.

• Make sure that the power supply is off before connecting or

disconnecting it to an auxilia device.

• Always use a properly rated voltage sensing device to confirm

power is o.

• Replace all devices, doors and covers before applying power to the

equipment.

Failure to follow these instructions will result in death or serious

inju.

Please make sure the main power in your facility is off before

installing

Get staed:

1. Open the clamp to see the arrow (P1→P2) or (K→L) or you can nd

it on the sticker on the outside of the clamp. This is the direction of

CT. The CT suppo bi-directional sensing. If the direction of the CT is

opposite to the direction of the current, the power will be negative.

2. Apply the CT on the electric cable and ensure the direction of CT is

correct when installing in dierent scenarios:

•To measure energy consumption

The arrow on the clamp should face to the correct direction of the

electricity current ows like CT1 in the wiring diagram. In this case,

the power will be positive, and the energy consumption will be

accumulated.

•To measure energy generation

The arrow on the clamp should face to inveer like CT2 in the wiring

diagram. In this case, the direction of the current is opposite to that of

the CT. The power will be negative, and the energy generation will be

accumulated.

Wiring diagram

For CT1:

If the measured current direction is K → L, the energy consumption is

accumulated as ‘From Grid’ energy.

If the measured current direction is L → K, the energy generation is

accumulated as ‘To Grid’ energy.

•To measure 'From Grid' or 'To Grid'

To monitor how much energy is pulling from and sending back from the

grid, install the CT on the leads coming from your mains like the CT1

below.

4Mounting

The Power Clamp has a mounting bracket for mounting purposes. You

can choose the following two mounting methods:

• Use the mounting bracket as template to mark the two holes on the

wall for installing screws. Screw the mounting bracket onto the wall

according to marked location. Install wall plugs if necessa.

• Sliding the mounting bracket through one end of the Din-Rail if you

want to x on the Din-Rail.

After the bracket is installed, snap the Power Clamp onto the bracket.

- If it still does not work, it is recommended to change the router and

t again.

- Ensure that the DHCP seice is enabled for the router. If not, the IP

address will be occupied.

- If your router supports both 2.4Ghz and 5Ghz, please enable the

2.4Ghz channel and add device under 2.4G Wi-Fi channel. You can

follow the following step on the App to congure the router.

2. Device oine

- Conrm whether the Power Clamp is powered on.

- Please conrm whether the home Wi-Fi network is normal, or whether

the Wi-Fi name and password has been modied:

Put the phone besides your device and make sure they are in the same

network environment, t to open a website to judge if the network can be

used.

- If there still have problems after the above checking, it is recommended

to remove the device or change the router to add it again.
